Embodiment 1

[0023] The special-shaped copper row 1 processing technology for hydraulic generator of the present invention comprises the following steps:

[0024] (1) According to the size and size requirements of the generator capacity, design the shape of the required special-shaped copper bar 1. The cross section of the copper bar 1 is "E" type. "Concave" type with rounded corners.

[0025] (2) Add electrolytic copper to the upper induction furnace for smelting, and add Ag and Bi to it, and adjust their content within their respective weight percentage ranges, Ag: 0.086%, Cu + Ag: 99.90%, and the rest is Bi: 0.0001%, Si: 0.0008%, Fe: 0.001% and other impurities. Melting temperature: 1200°C, smelting the required copper rod;

[0026] (3) Extrude the Φ20 copper rod on the continuous extrusion machine to produce a metal rod slightly larger than the required profile copper bar 1. The finished product size is 43.2*12.25mm and the extruded size is 45*14.85mm. The tensile strength after ext...

Abstract

The invention relates to a special-shaped copper bar, in particular to a special-shaped copper bar for the straight line part copper wire of a hydroelectric generator rotor, as well as its processing technology and application. The cross-section of the copper bar is "E" type, and the two copper bars are riveted into a double-hole hollow wire, which can achieve the effect of rapid water cooling. The invention adopts extrusion and cold drawing forming technology for production, has good electrical conductivity, high dimensional accuracy, fast water cooling, simple processing method, high yield and low cost, greatly reduces labor time and improves efficiency.

Description

technical field [0001] The invention relates to a special-shaped copper bar, in particular to a special-shaped copper bar for the straight line part copper wire of a hydroelectric generator rotor, as well as its processing technology and application. Background technique [0002] The continuous growth of hydraulic demand leads the continuous development of the hydroelectric generator industry. With the continuous improvement of generator manufacturing technology, the power of generators is getting larger and larger, and the overall technical level of generators is constantly improving. The platoon requirements are getting higher and higher. The special-shaped copper bar of the straight part of the rotor is a key component of the rotor of the hydroelectric generator. The two special-shaped copper bars are riveted through the copper wire fixing block of the intermediate rotor to jointly play the role of water cooling. At present, the special-shaped copper bars for the straigh...
